What this tracks
This dataset records the locations and details of roadside delineators (like reflective posts) installed on Tennessee interstates, state routes, and locally owned NHS routes.
Why it matters to you
If you frequently drive specific highway stretches (like I-40 near Dickson County), this data confirms where visibility aids like reflective posts are placed—helping you anticipate safer sections for night driving or bad weather. For trucking businesses, it highlights routes with updated safety infrastructure, which may influence dispatch routing decisions.
How to read this data
ROUTE — The highway identifier (e.g., “I0040” for I-40).
FEAT_DESC — Type of delineator (e.g., “Groundmounted Post”).
LOC_DESC — Placement relative to the road (e.g., “Right” for right shoulder).
DATE_COLL — When the data was last updated (e.g., “1426982400000” translates to March 2016).
Try it yourself
Check if your regular commute route (e.g., I-40 exit 172) has delineators by searching the dataset for the ROUTE and EXIT_ fields.
